The vendor holds no keys
Clio encrypts data and restricts access, but the service holds the keys and can process matters server-side. With Zeromatics, encryption happens in the browser under keys we never see.
Comparison
A Clio alternative
not even we can read.
Clio is the most mature legal practice management platform on the market. Zeromatics Legal asks one different question: should your software vendor be able to read your clients' matters at all?
Clio is a good product. This page is about one architectural difference — and who it matters for.
Side by side
Zeromatics Legal vs Clio
| Clio | Zeromatics | |
|---|---|---|
| Encryption & trust model | Encrypts data in transit and at rest, with restricted employee access. Keys are held by the service, so data can be processed server-side. | Zero-knowledge. Matters are encrypted in the browser under keys the vendor never holds — we mathematically cannot read client work. |
| Matter privacy | Matters live in shared firm storage; access is governed by application permissions. | Every matter is sealed under its own key. Sharing a matter means granting its key, and access is revocable like handing back a file. |
| Conflict checks | Firm-wide conflict search across matters and contacts. | Conflict checks run across the firm without disclosing client identities to people who should not see them. |
| Integration ecosystem | A large, mature App Directory with 250+ third-party integrations. | A focused, smaller set of integrations. Clio is clearly ahead here today. |
| Payments & billing | Mature integrated billing with Clio Payments — cards, ACH, digital wallets, payment plans. | Time, billing and invoicing are built in; payment-processor breadth is still maturing. Clio is ahead here. |
| Tasks & deadlines | Tasks, calendaring and court-rule deadline tools. | Tasks and hearing-preparation deadlines tie directly to the matter and stay encrypted under its key. |
| AI assistant | Clio Duo / Manage AI is powered by Microsoft Azure OpenAI — a cloud AI service. | Matter AI runs on self-hosted small language models on your infrastructure — privileged work never leaves for a public AI. |
| Private hosting | Delivered as a multi-tenant cloud service. | Privately hostable — run the whole platform inside your own jurisdiction and infrastructure. |
The difference that matters
Server-side encryption vs zero-knowledge
One key per matter
Confidentiality is enforced by cryptography, not by policy. Each matter is its own sealed envelope, shared by granting a key and closed by revoking it.
Privilege, by construction
If a breach or subpoena reaches the vendor, there is no readable client data to hand over. The architecture, not the contract, protects privilege.
To be fair
When Clio is the right choice
- You want the most mature, battle-tested legal practice management platform available today.
- A large third-party integration ecosystem is central to your workflow.
- You rely on Clio Payments and its broad set of payment methods and plans.
- Your firm prefers a turnkey cloud service over running infrastructure yourself.
If your data could appear in a headline, the architecture is the decision. That is where we are different.
